Hey All,

Outside of the nominal N20 noises I picked up on a harmonic thumping noise coming from about mid car (from the attached video you’ll hear this over the noise of the DI).

The video is at idle and in park. I cannot hear this while driving notice anything driving as well. I have zero codes or indicator lights, but I am asking if anyone has experienced this sound as well?

The only recent thing I’ve been troubleshooting has been stuttering/shuddering during WOT. I was thinking dirty injectors, but now hearing this I’m wondering is there something occurring in the drivetrain.

N20,85k, No modifications (had STG1 BM3 for 20k miles)

I feel like I hear ticking as well from under my ‘18 430i with the b46 motor. Let me know if you found anything out please.

I haven't found anything yet. The other note is that it disappeared, so I'm guessing this could be intermittent.
